Is ISO 68 and AW 68 the same?
AW 68 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 68. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 68 is on the heavier side for a hydraulic fluid which flows equivalent to a SAE 20 weight lubricant.
What is AW 68 hydraulic oil used for?
ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.
What is ISO 68 oil equivalent?
Obviously, SAE and ISO use two different scales to measure viscosity. SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.
What does 68 mean in hydraulic oil?
The viscosity of HLP 68 refers to the defined viscosity class of ISO VG (International Organization for Standardization Viscosity Grade). This describes that the kinematic viscosity of the hydraulic oil at 40 °C must be between 61.2 and 74.8 mm²/s. The centre point viscosity is exactly 68 mm²/s.
What is the viscosity of hydraulic oil 68?
Q8 HLVP 68 hydraulic oil is suitable for a broad range of applications and temperatures. The high viscosity index of >140 meets the industrial standard which results in an oil with good flow properties.
What viscosity is ISO 68?
ISO 3448 Viscosity class
| ISO 3448 Viscosity class | Kinematic viscosity at 40°C [mm2/s = cSt] | |

What is the difference between AW 46 and AW 68 hydraulic oil?
AW32 is approximately a 10 weight oil with the additives ▪ AW46 is approximately a 15 weight oil with the additives ▪ AW68 is approximately a 20 weight oil with the additives AW –provides many of the advantages of premium hydraulic oil at a moderate price.
Where can I use hydraulic oil 68?
Common applications for ISO 68 hydraulic oil include:
- machining headstocks.
- centralised lubrication systems.
- tipping gear.
- airline lubricators.
- lightly loaded reciprocating compressors.
What hydraulic oil is thicker 32 or 68?
32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.
